Can you explain what is meant by user identity verification process in a system?

The process of verifying a user's identity in a system is a set of actions aimed at confirming that the user truly is who they claim to be. It usually includes:

• Entering a login and password.
• Using additional factors (two-factor authentication), such as a code from SMS or an app.
• Biometric data (fingerprint, facial recognition).

The goal is to protect the system from unauthorized access. In Python, libraries for authentication and session management, such as Flask-Login or Django Authentication, are often used.

An example of a simple login and password check:

users = {'user1': 'password123'}

username = input('Enter username: ')
password = input('Enter password: ')

if users.get(username) == password:
    print('Access granted')
else:
    print('Invalid credentials')

In real systems, passwords are stored in encrypted form, and the process is more complex.
